Version 2 is coming very soon!


H-COUP v1 and v2: 1-min tutorial

• go to the H-COUP webpage.

• download the H-COUP file.

• (install LoopTools.)

• $ unzip H-COUP-2.0.zip

• edit Makefile to specify the PATH to LoopTools

• $ make (to compile)

• edit an input file (HSM, THDMs, IDM)

• $ ./hcoup (to run the program)

しかし、ヒッグスセクターの測定精度はまだまだ。

理論的にヒッグス2重項が1つである理由はなく、新物理模型の多くはヒッグスセクターの拡張を要請。

Since the BRs are correlated among all the decay modes,each model predicts a particular pattern of the deviations for each scenario.


BR(ττ) vs. BR(cc)

21

The measurement of h→cc is very important to disentangle the models.

ILC is necessary!


BR(ττ) vs. BR(WW)

22

Synergy• Higgs coupling precision measurements at the ILC • direct searches for additional Higgs bosons at the LHC• indirect searches in flavor experiments

• H-COUP v.1 was released in October, 2017.

- systematically calculates the renormalized 125GeV Higgs couplings at one-loop EW+QCD in various extended Higgs models (singlet extension, THDMs, inert doublet model).

• H-COUP v.2 will be released very soon.

- systematically calculates the 125GeV Higgs decay branching ratios at one-loop EW+QCD in various extended Higgs models (singlet extension, THDMs, inert doublet model).

• H-COUP v.3 ?

- other models? couplings/decays for additional Higgs bosons?- other renormalization schemes?- Higgs productions?- …
